Specification of Letters Patent.

Application filed March 23, 1921. Serial No. 45%657.

1 '0 all whom it may concern.

Be it known that I, Gnonen H. Power, a citizen of the United States, and a resident of Tulsa, in the county of Tulsa and State of Oklahoma, have invented certain new and useful Improvements in Sign Supports, of which the following is a specification.

My present invention relates generally to sign supports, and more particularly to a support for holding a sign in such manner that it may be effectively and advantageously displayed and will be capable of movement in such a manner as to attract the attention of those within view of the same.

More particularly my invention aims to provide a support permitting of attractive movement of a sign under the effect of air currents.

The primary object of my invention is the provision of a support for signs permitting of limited swinging movement, more especially oscillation of the sign with respect to the support and causing vertical shifting movement of the sign during its swinging movements or oscillations. In my improved arrangement it is contemplated that the sign itself shall constitute a vane against which air currents operate to oscillate the same and through the particular manner of its support, bring about vertical shifting movement.

In the accompanying drawing illustrating my present invention and forming a part of this specification,

Figure 1 is a perspective view showing the invention complete,

Figure 2 is a detail view of the upper end of: the support, partly broken away and in section,

Figure 8 is a top plan view, and

Figure l is a partial side view illustrating a slight modification Referring now to these figures and partic ularly to Figures 1 to 3 inclusive my inveiu tiou proposes a support for signs, as for up stance signs in the nature 01 a rectangular panel 10, the support including an upright 11. mounted at its lower end as for instance in concrete and the like 12, and provided adjacent to its upper end with a transverse pin 13 fixed diametrically therethrough with externally projecting ends adapted to cooperate with the notched lower end 14: of a tubular upper extension 15 whose lOWBllJOItlOIl telescopes the upper end of the upright 11. Projecting from the upper and lower ends of this tubular upper extension 15 are sign supporting arms 16 and 17, the latter projecting horizontally and the former inclining outwardly and downwardly as shown. These arms are joined at their outer ends and and the lower horizontal arm serves to support sign panel 10 as for instance by means of eye bolts 18.

The structure thus far described is present in both forms of the invention shown, the upright 11 and the upper extension tube 15 with its supporting arms 16 and 17, the latter supporting a sign panel 10 by means of eye bolts 18, being the same as the corresponding parts previously described in Figure 1.

In the construction of Figure 1, however, the upper end of the upright 11 is closed as shown in Figure 2 and has an upstanding eye bolt 19 with which the lower end of a spring 20 may be engaged. The upper end of this spring which extends upwardly within the tube 15 has connection with the lower eye 21 of an adjusting bolt 22 threaded vertically through the upper closed end of the tube 15 and provided. with a lock nut 23 serving to secure the same in adjusted position. This spring operates to create down.- ward tension upon the tube 15 and thus maintain the projecting ends of the pin 13 within the innermost portions of the grooves or recesses of the lower end. 1 1 oi? the tubular extension 15, it being observed that due to this structure oscillating movements of the tubular extension 15 under the effect of air currents against the sign panel, will bring about vertical movements oi the tube 15 under tension and controloi the spring 20.

According to the construction of Figure 4; the corresponding movements of the tiihu larextension 15 are controlled by a weight 24. in the upright 11? at the lower end of a flex ble connection whose upper end is secured at 26 to the tubular extension 15 the upper end of the upright 11* being in this form of the invention open to permit oi l'ree passage oi the weight supporting connection.

In either form of the invention it is obvious that oscillating movements of the sign panel, bringing about as they do vertical shitting movements thereof under ten-' of those within View of the sign and it is also obvious that these movements are proided for and take place without necessitating manual control or attention beyond mere regulation or adjustment from time to time.

It is also obvious that due to the above tacts the sign will be strong and durable in use and is economical both in first cost and upkeep.

It will further he noted that while the sign board may be mounted to normally stand at right angles to the line o'lf travel at a roadway or street side, it is also adapted to swing around to an angle sullieient to protect both support and sign board from being being blown down or otherwise injured in high winds. In fact the swinging lnOVBlIlBlli) of the sign board is unlimited in this respect, complete revolution being allowed.

I claim:

1. A sign connyrising a sign panel, a supporting upright, a tubular oscillatory exten sion telescoping the upper end of the upright and having recesses in its lower end provided with inclined walls, outstanding supporting arms carried by said tubular extension and to which the sign panel is con necteiilwherehy the latter may swing horizontally with the oscillations ot'said extension, a pin diametrically tln'ough the upright having its ends disposed in the recess of the masses id tubular extension to engage the inclined walls and force vertical shitting oi. said extension during oscillation, and means C011- nected at the upper end thereof to the tubular extension and exerting a downward pull on the same to yieldingly resist oscillating and "vertical shitting movements of the tubular extension and the sign panel with respect to the upright.

Q. A sign comprising a sign panel, a supporting upright, a tubular oscillatory extension telescoping the upper end of the upright and having recesses in its lower end provided with inclined walls, outstanding supporting arms carried by said tubular extension and towhich the panel is connected whereby the la or may swin horizontally with the oscillations oi said extension, a pin diametri- (sally through the upright having its ends disposed in the recesses of the said tubular extension to engage the inclined walls and force vertical shifting of said extension during oscillation aspring within the tubular extension connected at its lower end to the upright and adjustable means at the upper end of the extension to which the upper end oil? the spring is connected, whereby to adjustahly tension oscillating and :\'(?itical shitting movements of the tubular e2;- tension with respect to the upri 'ht.
